A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline is provided. The system includes a first portion of the pipeline including an upstream portion of the pipeline supplying a flow of fluid material and a flow restriction downstream of the first portion of the pipeline. The system further includes a second portion of the pipeline downstream of the flow restriction, receiving the flow of fluid material from the first portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline. The flow restriction is configured to create a lower pipeline internal pressure within the second portion as compared to a pipeline internal pressure within the first portion. The system further includes a third portion of the pipeline downstream of the environmentally sensitive area and including the downstream portion of the pipeline.

A check valve assembly for a supply pipe. The check valve assembly includes a hinge pin, a first flapper, and a second flapper. The first flapper is pivotally coupled to the second flapper with the hinge pin. The check valve assembly also includes a stopper located between the first flapper and the second flapper. The stopper is configured to limit movement of the first flapper and the second flapper. The check valve assembly further includes a plate assembly located downstream of the stopper. The plate assembly is configured to break vortices formed in a fluid flow across the first flapper and the second flapper.

High-pressure cryogenic fluid conduits that deliver high-pressure cryogenic fluids from a first point to a second point. This high-pressure fluid conduit has a safety feature that is activated when the high-pressure cryogenic fluid conduit fails due to exposure to a predetermined force. The safety feature is activated by the fracture of an annular ring that is positioned at either end of the high-pressure fluid conduit and is calibrated to fracture when exposed to the predetermined force. Fracture of the annular ring closes valves at each end of the high-pressure fluid conduit, thereby stopping the flow of high-pressure fluid from the high-pressure fluid source as well as the escape of high-pressure fluid from the high-pressure fluid container.

A pump connection point to a fracturing manifold includes a valve configured to isolate the fracturing manifold from an outside fluid source. A connector is attached to the valve opposite the well fracturing manifold. A guide is attached to the connector. The guide configured to align a fluid line to mate with the connector.

A sealing device is provided suitable for making at least partially fluid-tight a connection between a first pipe and a smaller second pipe, a part of the second pipe being able to be engaged in the first pipe while leaving an inter-pipes space between the two pipes in the radial direction. The sealing device is mounted on a supporting pipe and is adapted to spread out in the inter-pipes space from a guard position to a sealing position. It comprises at least one sealing set including substantially rigid movable sealing members which extend each along a predetermined angular sector in a circumferential direction and are individually guided in displacement between the guard position and the sealing position.

A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline includes an upstream portion of the pipeline supplying a flow of fluid material, a crossing portion of the pipeline receiving the flow of fluid material from the upstream portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline, the downstream portion, a pipeline pressure activated valve selectively capable of blocking the flow of fluid material from entering the crossing portion based upon a change in pressure within the crossing portion, and a fluid capacitor connected to the upstream portion configured to filter out a pressure spike in the upstream portion associated with the valve blocking the flow of fluid material.

Systems and methods for dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.

To provide a pipe joint that can immediately shut off a hydrogen gas flow path at an initial stage when a plug (nozzle side member) comes out of a socket (filling apparatus side member) to prevent release of outgas. A pipe joint (100) of the present invention includes: a cylindrical nozzle side member (10) with a shutoff valve (5), in the cylindrical nozzle side member (10) being formed a passage (1A); and a cylindrical filling apparatus side member (20) with a shutoff valve (24), in the cylindrical filling apparatus side member (20) being formed a passage (21A), wherein when the nozzle side member (10) and the filling apparatus side member (20) are connected with each other, central axes of the passages (1A, 21A) of the nozzle side member (10) and the filling apparatus side member (20) do not form a same straight line, and the central axes of the passages (1A, 21A) are offset without intersecting, and the shutoff valves (5, 24) of the both members (10, 20) open to communicate the passages (1A, 21A) of the both members (10, 20) with each other, and when the nozzle side member (10) is separated from the filling apparatus side member (20), the shutoff valves (5, 24) of the both members (10, 20) close.

A pump connection point to a fracturing manifold includes a valve configured to isolate the fracturing manifold from an outside fluid source. A connector is attached to the valve opposite the well fracturing manifold. A guide is attached to the connector. The guide configured to align a fluid line to mate with the connector.

There is described a pipe apparatus having two circular coaxial layers, inner and outer, defining an annular gap therebetween. At least one segmentation ring with a predesigned opening is placed within the annular gap. The pipe system is composed of interconnected pipe apparatuses of the same type. Compact wireless stations are embedded in the segmentation rings within sealed predesigned openings forming a wireless information and communication network (WICN). Each segmentation ring incorporates a pressure relief mechanism. When a layer of a given pipe apparatus breaks and fluid leaks into the annular gap in a given segment, the segmentation rings surrounding that segment temporarily retain the fluid and the WICN is disturbed in the affected area. At least one external central unit monitors WICN activity and integrity inside the pipe system and detects such leakage, before the leak spreads to another segment of the pipe system, without reaching the outside environment.
